Abstract
Emergence and distribution of the eolian processes in the arid and semiarid zones of Eurasia depends on the location of the polar front dividing temperate (polar) and tropic air masses. It has in general latitudinal orientation between 30° and 50° N. From time to time a blocking anticyclones are formed which brake dominating west winds. In the result the main stream is divided into two branches: the northeastern and southeastern ones of approximately even intensity. The zonal process is changed to meridional ones, which lead to increase in the temperature contrasts and conduces to cyclogenesis along the anticyclone periphery. In Eurasia there are several areas of present intensive eolean processes, their location being determined by the position of blocking Asian anticyclone and convergent zones at its periphery: 1) steppes of the East Europe, 2) steppes of the West Siberia and the Northern Kazakhstan in the moderate zone, 3) the East Asian zone, 4) The Middle Asian zone (subtropics).
